Abstract: 1,150,005. Welding by pressure. NORTH AMERICAN AVIATION Inc. 9 Aug., 1966 [9 Aug., 1965], No. 35649/66. Heading B3R. A method of bonding a ferrous member to an aluminium or aluminium-based member comprises providing a tapered or knife edge on the ferrous member and pressing this edge into the aluminium member at elevated temperature. The process is preferably carried out with the joint faces under vacuum or in inert gas and the pressure and temperature may be maintained for a period of about 3 to 30 minutes. Temperatures of 750-1200‹ F. and pressures of about 20,000-35,000 p.s.i. are envisaged. In order to prevent undesirable intermetallic diffusion occurring a barrier metal comprising one or more of the following: tantalum, niobium, chromium, gold, silver, nickel, tungsten and molybdenum may be interposed between the ferrous and aluminium members. The barrier metal may be applied as a separate foil or be coated on either the ferrous or aluminium member. The ferrous member may be of stainless steel and comprises at least 50% iron while the aluminium based member may be of an alloy containing 4-12% aluminium oxide dispersed in aluminium. The invention is particularly applicable to the joining of tubular ferrous and aluminium members 2, 4, the former having a knife edge 6, the members being supported by an outer die 10 and inner mandrel 12 on a die base 14. The assembly is heated by an induction coil 16 and pressure applied by an hydraulic press 18. The whole apparatus is enclosed in a vacuum or inert gas enclosure during the bonding process.

Abstract: 1441074 Pile drivers RAYMOND INTERNATIONAL Inc 14 Aug 1974 [27 Aug 1973] 35822/74 Heading B3H A pile driver particularly for underwater operation comprises a casing with a ram 60 mounted slidably therein for impacting an anvil 114 and hydraulic circuitry for pressurizing annular chambers 82, 84 to effect a working stroke, the chambers 82, 84 being separated from the end chambers 180, 182 of the casing by seals 74, 78. The end chambers 180, 182 are interconnected by an axial bore 94 through the ram 60. The anvil 114 has a stem 118 which projects out of the casing through a seal 112. The ram is formed with a lower section 60c which defines the lower chamber 84, an upper section 60a of smaller diameter and which defines the upper chamber 82 and an intermediate portion 60b. During a stroke of the ram hydraulic fluid is allowed to flow freely along the axial bore 94 between the chambers 180, 182. A transverse set of bores 96 lead to an intermediate annular chamber from the axial bore 94. The hydraulic circuitry, Fig. 6, includes a main switching valve 40, an upstroke pilot valve 42, a downstroke pilot valve 44 and a latching pilot valve 46. Hydraulic pressure is applied from a pump 130 to a line 140 leading to the lower annular chamber 84 to raise the ram 60. During raising of the ram 60 transverse ports 104, 102 in the casing are successively communicated to the lower chamber 84 to pressurized lines 162, 170 successively to operate valves 42, 44. Opening of the valves 42, 44 pressurizes line 150 to open valve 40 and pressurize line 148 leading to the upper chamber 82. The ram then descends due to the differential pressure and transverse ports 102, 104 are connected to the axial bore 94 through the bores 96 in turn. This causes line 150 to be connected to drain and valve 40 to connect line 148 to drain. This is timed to occur just before, just after or just as the ram strikes the anvil. If desired an hydraulic delay arrangement may be included in the line 162.

Patent GB-1090877-A (GB)
Title: Method and apparatus for removing liquids from fibrous articles
IPC: D21F3/10
Filed: 1964-09-03
Abstract: The liquid content of a wet fibrous article is reduced by pressing on to it a resilient body formed of polyamide particles and having a porosity of at least 15%, the pores being capillary in size and then removing from the polyamide body liquid transferred to it from the wet fibrous article.  The article to be treated may be a web from a papermaking machine or a liquid-treated web.  The polyamide body may be formed by sintering from particles of average diameter no more than 40 microns, and may be the surface of a roll, a platen or a die form.  The liquid may be removed from it by applying vacuum to the same surface to which the wet article is applied, or to the other surface.  Five embodiments are described.  In the first (Figs. 1-3, not shown) paper from a wet press is passed through one or more presses each comprising a nonporous roll and a porous nylon roll. The latter comprises a number of porous rings mounted on a hollow, cylindrical, perforated roll mounted on a hollow perforated shaft. Vacuum is applied to the end of the shaft to withdraw liquid from the roll.  In a second embodiment (Figs. 4 and 5, not shown), the press is like that of Fig. 1, but the roll comprises a continuous sleeve of porous nylon fitted on a metal shaft with circumferential grooves, communicating through longitudinal channels, and radial channels with a central channel to a vacuum source.  In the third (Fig. 6, not shown) a sleeve of porous nylon is mounted on a solid shaft.  A vacuum chamber is mounted to contact the surface of the roll after it has separated from the wet web, and so to remove liquid from it.  In the fourth embodiment (Fig. 7, not shown), suitable for pressing flat paperboard, the wet board is placed between two flat sheets of porous polyamide.  These are then placed between two perforated platens and pressed while vacuum is applied to the space above the upper platen. In the fifth embodiment (Figs. 8 and 9, not shown) four forming dies are rotatably mounted on retractable arms on a shaft.  Vacuum or compressed air can be applied through each arm. Each die in turn is immersed in a tank of fibrous slurry, white vacuum is applied to form a fibrous mat.  Each die is then rotated until it is opposite a complementary form in a wheel.  This form comprises a shaped body of porous nylon on a perforated support plate with a vacuum chamber behind it.  The fibrous web is transferred from the die to the complementary form, and when its liquid content has been sufficiently reduced is again transferred to a conveyor which takes it to a dryer.

Title: Improvements in or relating to tuner mechanisms for radio receivers
IPC: H03J7/30
Filed: 1954-12-15
Abstract: 769,349. Tuning radio receivers. GENERAL MOTORS CORPORATION. Dec. 15, 1954 [Jan. 8, 1954], No. 36337/54. Class 40(5) The tuning carriage of a stop-on-signal radio receiver is movable manually as well as automatically, the automatic movement being effected against the action of a spring by repetitive rotary movements of a solenoid under the control of means which stops the timing when a signal is tuned in Fig. 2 shows three tuning coils of a radio receiver having their adjusting cores 22, 24, 26 mounted on a carriage 28 which is reciprocable along a guide 36. The carriage is driven by a solenoid type motor 46 . (Fig. 4) which repetitively rotates a small amount causing an arm 52 to respectively rotate a sector gear 54. This gear is provided with ears 66, 70 which at the limits of its movement engage a contact arm 72 which de-energizes the motor until a spring 60 has restored the sector gear to its original position. The sector gear 54 (Fig. 3) drives a pinion 80 and thus through a ratchet and pawl mechanism 84 a large gear-whee 18 and a pinion 92. The large gear-wheel drives an air brake governor 208, 204 and the pinion drives a planet gear-wheel 110 mounted on an arm 108 on a disc 106 freely rotable the shaft 82. The planet gear 110 is attached to a pinion 112 which drives a further gearwheel 114. This drives a cam 116 which is associated with a cam follower 130 (Fig. 2) carried by an arm 124. This arm has a fixed pivot 126 at one end and the other end is connected to the tuning carriage through a link 122. The cam 116 is shaped to produce two reciprocations of the carriage during each complete rotation. When a signal is tuned in a solenoid 184 (Fig. 4) is energized to operate an arm 188 (Fig. 4) which engages the air governor 206 to arrest the tuning. Manual tuning is effected through a flexible drive 160 (Fig. 2) which is connected to a worm wheel 156 engaging a large gear-wheel 102 (Fig. 3). This gear-wheel is supported on arms 104 on the disc 106. Accordingly when it is rotated by the worm wheel it causes the disc 106 to rotate and since the pinion 92 is locked at the air brake, the planet gears 110 and 112 revolve causing the gearwheel 114 and the cam rotate. A tuning indicator is provided comprising a pointer 142 (Fig. 2) supported on an arm pivoted at one end in a slot 48 and coupled to the tuning carriable by a bell crank lever 134 and a link 132.

Class 98(1) A panoramic camera comprises a rotor' including two reflectors, a lens assembly, shutter means, and diaphragm means and a rotary frame holding a film cylindrically concentrically with the rotor, and means to wind the film from a spool on to the rotary frame and at the same time to rotate the rotor through a corresponding angle up to 360 degrees. As shown, the rotor 4, which has a spindle 3 carried in ball bearings 19 includes the reflectors 33 .and 8, a lens assembly 5, a shutter 6 and a diaphragm 7. The rotary frame 10 is carried in ball bearings 49, 50 and has a radius equal to the focal length of the lens assembly 5. The upper reflector 33 may be held at an angle of 45 degrees by the stays 28, 29 or may be folded down to provide a lid for the camera body 1. The lower end of the bearing case 2 is surrounded by a spiral spring 20 fixed at one end to the bearing case and at the other to the gear 21 fixed to the end of the spindle 3 and meshing with a gear 24 on a square shaft carrying a sprocket 14 engaging the perforated film 11. When the film is wound by operation of the knob 15 turn ing the film take-up spool, it passes from a cartridge round a guide roller, the frame 10 and the sprocket 14 to the spool, and at the same time the gear 24 rotates the gear 21 and hence the rotor 4 against the action of the spring 20. When the mirror 33 is erected, an image is reflected through the lens 5 and when the shutter 6 is opened, on to the reflector 8 and thence through a slit on to the film 11. When the shutter button 34 is pushed up to open the shutter and start the exposure, the gear 24 is disengaged from the gear 21 and the rotor 4 turns back to its original position, in so doing exposing the whole surface of the film 11 wound round the frame 10. The rotor 4 is finally stopped by the engagement of the springy member 17 with the stop 18. The winding of the film 11 by the knob 15 can be interrupted at any desired point to obtain a picture extending over the corresponding angle less than 360 degrees. A modification of the camera is described for use with unperforated film.

Abstract: 1,014,318. Electronic counters. HEWLETT-PACKARD CO. Sept. 17, 1963 [Oct. 1, 1962], No. 36631/63. Heading G4A. A binary-coded decimal counter has the inputs to a number of stages controlled by logic circuits which are in turn controlled by the settings of various stages. Gates 9, 11, 21, 27, 31 require the application of one or two potentials of the polarity indicated. Binary A enables gates 9, 11 alternately so that evennumbered pulses pass to amplifier 19. At zero the right-hand side of all the binaries has a +ve output. The second pulse therefore passes 21 to set binary B and the fourth passes 31 to set C also, so enabling 27. The sixth pulse restores B to produce a pulse on lead 33 which sets D. The eighth pulse again sets B to re-enable 27 so that the tenth pulse restores B, D and C in succession. An output pulse may be obtained at 37 for frequency-dividing purposes. Alternatively the count may be indicated by combinations of outputs from all four binaries.
